java regex "^" and "\A" difference

Question

I'm new to regex. I try to research it.

I am reading following article:

http://www.tutorialspoint.com/java/java_regular_expressions.htm

snippet from article:

^   Matches beginning of line.

and

\A  Beginning of entire string

I don't understand the difference. Can you clarify this ?

Answer 1

Difference is apparent when you use MULTILINE switch where ^ is matched at start of every line but \A is still matched only once at start of very first line.
